Tomei has advanced technology
Since our founding, we have faced many difficult problems together with our customers as a pioneer and developed products.
We will continue to work together with our customers to solve problems by utilizing the know-how of "materials," "technology," and "quality" that we have cultivated through this experience.
We are challenging new possibilities by doping boron into diamond, which is an insulator and does not conduct electricity, and using it as a diamond electrode.
Generates ozone water
Generates ozone water, which is safe and environmentally friendly Provides packages in the form of cells (modules) Supports from the material field Strengths of in-house development
Ozone water can be generated by electrolysis of water using conductive diamond electrodes. Ozonated water is water that contains ozone and OH (hydroxyl radical) dissolved in it, and is highly effective in sterilizing, killing viruses, and decomposing persistent organic matter. When compared to air and water, ozone dissolved in water has more molecules and is more effective at the same concentration.
It is also safer than ozone gas, easier to handle because it is a liquid, and more effective on the target object.
We provide the most suitable products for customers from a wide range of products.
DIAMOND POWDER for industrial uses that has been subjected to a high level of process and quality control. It is used as a material for precision processing tools in the fields of semiconductors, automobiles, machinery, and civil engineering and construction.Other product list
Diamond sintered compact
PCD is a tool and wear-resistant material made by sintering diamond powder and cemented carbide using a high-temperature, high-pressure method. It has higher toughness than single-crystal diamond, and is used as a material for cutting and grinding tools for non-ferrous metals in the automotive and mechanical fields.Other product list
cBN sintered body
This is a tool material made by sintering cBN powder mixed with binder and cemented carbide using a high-temperature, high-pressure method. It is used as a material for cutting and grinding tools for ferrous metals in the automobile and machinery fields.Other product list
Special sintered body
This is a special sintered body product that utilizes our own high-temperature, high-pressure synthesis equipment. We also handle sintered bodies in large sizes. These are special diamond sintered bodies intended to replace cemented carbide tools in the automotive and mechanical fields.Other product list
